Are you sure the cooler is mounted correctly?
The FX-6 series shouldn't hit tempretures above 70c since they start throtteling there, somethings wrong with your setup.
So just the cheapest dual core would be been efficent enough in other words. No need to make a statement like overclocking and buying a more powerful CPU makes it so you can do better programming.
Stick with what is actually true.
But as you said, no one can see in the future.
Unless you believe there's another dimension and someone miracelously traveled back in time and is a user on this forum, no one can tell you.
Using Greenshot myself frankly I don't see the point with puuush when they delete your images after 30days.
Would have used Gyazo instead then because of that nifty gif and video support.
